1. Gibbons are the closest relatives of a person who create couples for life. Their unions are unusually strong, and they exhibit low sexual dimorphism, meaning males and females are about the same size. This is proof of the fact that both sexes have approximately the same rights in relationships.
2. Swans form monogamous pairs that exist for many years, and in some cases for a lifetime. Their devotion is so well described in the literature that the image of two swimming swans with their necks curved in the shape of a heart has become an almost universal symbol of love.
3. Black vultures. A pleasant appearance is not a prerequisite for a committed relationship. Black vultures confirm this fact. They have been known to attack other vultures when they begin to whore.
4. French bristle tooth.
It is unlikely that you will ever find a French bristletooth alone - these creatures live, travel and even hunt in pairs. These fish form monogamous bonds that often last as long as the partners live. Moreover, they act as a team, resolutely defending their territory from neighboring pairs.
5. Wolves. In folklore, wolves are portrayed as crooks and swindlers, but in reality these animals lead a family life that is more faithful and pious than many relationships between people. As a rule, packs consist of males and females and their offspring, which, in essence, makes wolf packs look like a nuclear family.
6. Albatrosses
An albatross can fly a long distance over the ocean, but despite such long journeys, this bird will always return to the same place - and to the same partner - when it is time to breed. Bonds between males and females are formed over several years and last a lifetime, held together by stupid but loving ritual dances.
7. Tremites. In an ant colony, the uterus mates with one or more males, stores gametes all its life, and the male ant dies shortly after mating. In contrast, male and female termites can mate for life, literally giving life to an entire kingdom.
8. Steppe voles
Although most rodents are promiscuous, prairie voles break that reputation by forming typically monogamous pairs that sometimes last a lifetime. Moreover, prairie voles are considered an animal model of monogamy in humans. They snuggle and groom each other, share nesting and raising responsibilities, and generally display a high level of supportive behaviour.
9. Pigeons. In many works, turtledoves appear in pairs, and over time they have become a symbol of love and devotion. They even inspired Shakespeare to write The Phoenix and the Dove.
10. Bald eagles.
They are the national emblem of the United States, and when it comes to maintaining relationships, bald eagles rise much higher than the country they symbolize. As a rule, bald eagles create couples for life, except in cases of death or impotence of a partner.
